Abstract

We present the design of the trigger system for the KLOE experiment at the Frascati phi-factory DAFNE. The detector consists of a large volume drift chamber and a calorimeter both immersed in a 0.52 T solenoidal field. The trigger, structured with a first- and a second-decision level, is based on multiplicity of energy deposits in the calorimeter and of hits in the drift chamber. The selection criteria are described and the efficiency for detecting phi decays are evaluated with the data collected during the first runs.

Abstract

We have measured the ratio R-S(pi) = Gamma(K-S --> pi(+)pi(-)(gamma))/Gamma(K-S --> pi(0)pi(0)) with the KLOE detector at the DAPhiNE e(+)e(-) collider. This measurement is fully inclusive with respect to the pi(+)pi(-)gamma final state. The sample of over 106 two-pion decays of tagged K-S mesons allows a statistical error as low as similar to 0.1% to be obtained. The accuracy is limited by systematic uncertainties, which are estimated primarily from data. We find R-S(pi) = 2.236 +/- 0.003(stat) +/- 0.015(syst). (C) 2002 Elsevier Science B.V.

Abstract

We have measured the radiative decays φ→ηγ, φ→η′γ selecting π+π−γγγ final state in a sample of ∼5×107 φ-mesons produced at the Frascati φ-factory DAΦNE. We obtain Γ(φ→η′γ)/Γ(φ→ηγ)=(4.70±0.47±0.31)×10−3. From this result we derive new accurate values for the branching ratio BR(φ→η′γ)=(6.10±0.61±0.43)×10−5 and the mixing angle of pseudoscalar mesons in the flavour basis ϕP=(41.8+1.9−1.6)°.

Abstract

In a sample of 5.3x10^7 ∅-decays observed with the KLOE detector at the Frascati ∅-factory DAF∅NE we find 605 ηπ^0γ events with η→γγ and 197 π^0γ events with η→π^+π^-π^0. The decay ηπ^0γ is dominated by the process ∅→a_0γ.From a fit to the ηπ^0 mass spectrum we find BR(∅→ηa_0(980)γ)=(7.4±0.7)x10^{-5}.

Abstract

The construction of the KLOE lead-scintillating fibres electromagnetic calorimeter has been completed. The final results of the extensive quality checks of all the calorimeter modules are presented here. The measurements have been done in the Frascati Laboratories at a cosmic ray test facility using minimum ionizing particles. The results show that all the calorimeter modules are well fulfilling the design specifications concerning time and energy resolutions. Furthermore, by using the same cosmic ray facility, all the calorimeter elements have been also pre-calibrated.

Abstract

We present a study of the reaction e+e- --> pi+pi-pi0 at the phi peak W=M(phi)=1019.4 MeV observed with the KLOE detector at Dafne. The reaction is dominated by phi production and decay, e+e- --> phi --> pi+pi-pi0. From a fit to the Dalitz plot density distribution we obtain the rho-meson parameters for its three charge states. We also find the relative amplitudes for phi --> rhopi and phi -> pi+pi-pi0 and the cross-section for e+e- --> omega pi0 with omega --> pi+pi-.

Abstract

The main goal of the KLOE experiment at the Frascati DAΦNE φ − factory is the study CP violation in kaon decays. The tracking device of the experiment is a drift chamber whose dimensions, 4 m of diameter and 3.3 m length, provide a large acceptance volume for the decay products of low momentum K L ( λ L =3.4 m ). A complete stereo geometry with 12.582 cells arranged in 58 layers guarantees a high and uniform efficiency in the reconstruction of the charged K L decays. Very light materials have been chosen both for the drift medium, a helium-based gas mixture, and for the mechanical structure, made of carbon fiber, to minimize multiple scattering and conversion of low-energy photons. The design requirements, the adopted solutions together with the calibration procedure and the tracking performances of the drift chamber are discussed.

Abstract

Test beam results of a full scale barrel prototype of the KLOE electromagnetic calorimeter satisfied the experimental requirements, so initiating the calorimeter mass production. At the Frascati National Laboratory of INFN a test stand was set up to use cosmic rays for quality control and first calibrations of the modules produced in mass construction. The results show that the fibers and photomultipllers performances exceed our expectations. Combining cosmic rays and test beam measurements a time resolution of 55 ps/√E(GeV) and an energy resolution of 4.7%/√E(GeV) are expected for electromagnetic showers. The end of modules assembling and calibration is foreseen for the early 1997.

Abstract

The design and the status of construction of the KLOE electromagnetic calorimeter are described in this report. 18 out of 24 barrel modules have been fully assembled and more than 50% of the end-cap, modules are built. All experimental specifications are fulfilled as shown by the test beam results of the final size prototype. Since the quality of fibers and photomultipliers have gone through improvements, the final calorimeter performances will exceed our expectations. The main parameters of each calorimeter module (light yield, attenuation length and time resolution) are fully surveyed using cosmic rays. Extrapolating the results to electromagnetic showers, a time resolution of 55 ps/root E(GeV) and a resolution of 0.9 cm/root E(GeV) an the coordinate along the fibers are obtained. An energy resolution of 4.7%/root E(GeV) can also be quoted.

Abstract

Background & Aims Assessment of long-term outcome is required in hepatitis C virus (HCV)-infected patients with cirrhosis, who have been successfully treated for Barcelona Clinic Liver Cancer (BCLC) stage A hepatocellular carcinoma (HCC). However, problems arise due to the lack of models accounting for early changes during follow-up. The aim of this study was to estimate the impact of early events (HCC recurrence or hepatic decompensation within 12Âmonths of complete radiological response) on 5-year overall survival (OS) in a large cohort of patients with HCV and cirrhosis, successfully treated HCC. Methods A total of 328 consecutive Caucasian patients with HCV-related cirrhosis and BCLC stage 0/A HCC who had complete radiological response after curative resection or thermal ablation were prospectively recruited to this study. Primary endpoint of the study was 5-year OS. Independent baseline and time-dependent predictors of 5-year OS were identified by Cox model. Results The observed 5-year survival rate was 44%. The observed HCC early recurrence and early hepatic decompensation rate were 21% and 10%, respectively. Early hepatic decompensation (Hazard Ratio [HR] 7.52; 95% confidence intervals (CI): 1.23–13.48) and HCC early recurrence as time-dependent covariates (HR 2.50; 95%CI: 1.23–5.05), presence of esophageal varices at baseline (HR 1.66; 95% CI: 1.02–2.70) and age (HR 1.04; 95% CI: 1.02–1.07) were significantly associated with the 5-year OS. Conclusion Survival in HCV-infected patients with cirrhosis and successfully treated HCC is influenced by early hepatic decompensation. Our study indirectly suggests that direct-acting antiviral agents could improve OS of HCC patients through long-term preservation of liver function, resulting in a lower cirrhosis-related mortality and a greater change of receiving curative treatments. Lay summary Survival in hepatitis C virus (HCV) infected patients with cirrhosis and successfully treated hepatocellular carcinoma (HCC), is mainly influenced by early hepatic decompensation. HCV eradication after treatment with new direct-acting antiviral agents could improve overall survival of HCC patients through long-term preservation of liver function.

Abstract

The Frascati e +e - collider, DAΨNE, operates at a center of mass energy of ∼1020MeV, the mass of the φ-meson. Three detectors have been realized, KLOE, DEAR, and FINUDA. The first two are presently collecting data in the two DAΨNE interaction regions (IR), while the third is being assembled in its pit inside the DAΨNE hall and will take data in the IR occupied by DEAR. The KLOE experiment, which is designed to measure CP and CPT violation parameters in the K SK L system, has collected so far ∼300 pb -1. Measurements obtained using the year 2000 data sample will be presented, which are focussed on K S physics and φ radiative decays. The DEAR experiment aims at studying the scattering lengths of the kaon-nucleon system, through a precise measurement of the K α line shifts in kaonic hydrogen and kaonic deuterium. With 2001 and 2002 data-taking periods the DEAR collaboration has demonstrated the capability of creating and detecting exotic atoms using the kaon flux from DAΨNE, by measuring the X-ray spectrum of kaonic nitrogen. The present status and perspectives of the DEAR experiment will be discussed. A brief report will be given at the end on the FINUDA physics program, aiming at the study of the A-hypernuclei levels and lifetimes.

KLOE KS meson
Abstract

We present a measurement of the branching ratio BR(K-S --> pi(+/-)e(-/+)v(v)) performed using the KLOE detector. K-S-mesons are produced in the reaction e(+)e(-) --> phi --> KSKL at the DAPhiNE collider. In a sample of similar to 5 x 106 K-S-tagged events we find 624+/-30 semileptonic K-S decays. Normalizing to the K-S --> pi(+)pi(-) count in the same data sample, we obtain BR(K-S --> piev) = (6.91+/-0.37) x 10(-4), in agreement with the Standard Model expectation.

Abstract

In a sample of 5.3 x 10(7), phi-decays observed with the KLOE detector at the Frascati phi-factory DAPhiDNE we find 605 etapi(o)gamma events with eta --> gammagamma and 197 etapi(o)gamma events with eta --> pi(+)pi(-)pi(o). The decay etapi(o)gamma is dominated by the process phi --> a(o)gamma. From a fit to the etapi(o) mass spectrum we find BR(phi --> a(o)(980)gamma) = (7.4 +/- 0.7) x 10(-5).

Abstract

The main goal of the KLOE experiment at the Frascati DAPhiNE phi -factory is the study CP violation in kaon decays. The tracking device of the experiment is a drift chamber whose dimensions, 4 m of diameter and 3.3 m length, provide a large acceptance volume for the decay products of low momentum K-L (lambda(L) = 3.4m). A complete stereo geometry with 12.582 cells arranged in 58 layers guarantees a high and uniform efficiency in the reconstruction of the charged K-L decays. Very light materials have been chosen both for the drift medium, a helium-based gas mixture, and for the mechanical structure, made of carbon fiber, to minimize multiple scattering and conversion of low-energy photons. The design requirements, the adopted solutions together with the calibration procedure and the tracking performances of the drift chamber are discussed. (C) 2002 Published by Elsevier Science B.V.

Abstract

Purpose: The prognosis of patients with unresectable hepatocellular carcinoma (uHCC) and compensated cirrhosis is influenced by cancer progression. Data on the incidence and the prognostic role of clinical hepatic decompensation following immune checkpoint inhibitor therapy are lacking. We aimed to assess whether early clinical hepatic decompensation (CHD) within 3 months from commencement of systemic therapy affects overall survival (OS) of patients treated with Atezolizumab plus Bevacizumab or Sorafenib., Patients and Methods: Individual patient data from IMbrave150 trial were analyzed. Cumulative incidence of CHD was assessed by competing risks analysis against HCC radiological progression. Early CHD and HCC radiological progression were assessed as predictors of OS by time-dependent Cox model., Results: The 3- and 12-month rates of CHD were 7% and 12%, respectively, while the 3- and 12-month rates of HCC radiological progression were 23% and 52%. Albumin-bilirubin(ALBI)grade 2 (Sub-distribution hazard ratio[sHR] 1.79, 95%CI 1.01-3.19, p=0.049), INR(sHR 1.97, 95%CI 1.64-2.37, p<0.001) and presence of neoplastic macrovascular invasion (sHR 2.01, 95%CI 1.14-3.54, p=0.020) were independently associated with higher risk of CHD. Early CHD(HR 7.56, 95%CI 4.47-12.8) and early HCC radiological progression(HR 5.92, 95%CI 4.03-8.69), as first events, were independently associated with higher mortality., Conclusions: This study provides robust evidence that early CHD is associated with the highest risk of death in patients with uHCC undergoing systemic treatment. Within well-compensated participants, ALBI, INR and macrovascular invasion identify a population at higher risk of decompensation. Inclusion of clinical decompensation events in future prospective clinical trials may improve characterization of OS from systemic therapy of HCC.

Abstract

Background and Aims: Patients with overt or occult hepatitis B virus (HBV) infection receiving immunosuppressive treatments have a wide risk of HBV reactivation (HBVr). We performed meta-analysis with decision curve analyses (DCA) to estimate the risk of HBVr in HBsAg-negative anti-HBc-positive patients naïve to nucleos(t)ide analogues (NAs) receiving immunosuppressive treatments., Approach and Results: Studies were identified through literature search until October 2022. Pooled estimates were obtained using random-effects model. Subgroup analyses were performed according to underlying disease and immunosuppressive treatments. DCA was used to identify the threshold probability associated with the net benefit of antiviral prophylaxis in HBsAg-negative anti-HBc-positive patients. We selected 68 studies (40 retrospective and 28 prospective), including 8034 patients with HBsAg negative anti-HBc positive. HBVr was 4% (95% CI 3%-6%) in HBsAg-negative anti-HBc-positive patients, with a significantly high heterogeneity (I 2 69%; p < .01). The number-needed-to-treat (NNT) by DCA ranged from 8 to 24 for chemotherapy plus rituximab, from 12 to 24 for targeted therapies in cancer patients and from 13 to 39 for immune-mediated diseases. Net benefit was small for monoclonal antibodies., Conclusions: Our DCA in HBsAg-negative anti-HBc-positive patients provided evidence that NA prophylaxis is strongly recommended in patients treated with chemotherapy combined with rituximab and could be appropriate in patients with cancer treated with targeted therapies and in patients with immune-mediated diseases. Finally, in patients with cancer treated with monoclonal antibodies or with chemotherapy without rituximab, the net benefit is even lower., (© 2024 The Author(s).

Abstract

Introduction: The most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC. This real-world study aimed to compare outcomes reached by lenvatinib and sorafenib second-line therapy in this setting., Methods: The overall cohort included 891 patients with HCC from 5 countries treated with atezolizumab plus bevacizumab in first-line setting between October 2018 and April 2022. At the data cut-off (May 2022), 41.5% of patients were continuing a first-line treatment, 5.5% were lost at follow-up, and 53.0% of patients had progressive disease after first-line therapy. 51.5% of patients with progressive disease received a second-line treatment, while 48.5% did not receive any subsequent therapy. Between patients receiving second-line treatment, 11.1% of patients underwent transarterial chemoembolization, 21.0% received sorafenib, 35.4% underwent lenvatinib, and 32.5% were treated with other drugs., Results: Lenvatinib second-line subgroup achieved a median overall survival (mOS) of 18.9 months, significative longer (p = 0.01; hazard ratio [HR]: 2.24) compared to sorafenib subgroup that reached a mOS of 14.3 months. The multivariate analysis highlighted albumin-bilirubin 1 grade (p < 0.01; HR: 5.23) and lenvatinib second-line therapy (p = 0.01; HR: 2.18) as positive prognostic factors for OS. The forest plot highlighted a positive trend in terms of OS in favor of patients treated with lenvatinib second-line regardless of baseline characteristics before first-line therapy., Conclusion: These results suggest that, in patients with HCC progressed to first-line atezolizumab plus bevacizumab, lenvatinib second-line therapy is associated to an improved survival compared to sorafenib., (© 2024 S.

Abstract

Background: Delays and limitations of palliative care in patients with liver transplantation- ineligible end-stage hepatocellular carcinoma according to Barcelona Clinic Liver Cancer staging system may be explained by different perceptions between hepatologists and palliative care physicians in the absence of shared guidelines., Aim: To assess physicians' attitudes toward palliative care in end-stage hepatocellular carcinoma and to understand what the obstacles are to more effective management and co-shared between palliative care physicians and hepatologists., Design: Members of the Italian Association for the Study of Liver Disease and the Italian Society of Palliative Care were invited to a web-based survey to investigate practical management attitude for patients with liver transplant- ineligible end-stage hepatocellular carcinoma., Participants: Physician members of the of the two associations, representing several hospitals and services in the country., Results: Ninety-seven hepatologists and 70 palliative care physicians completed the survey: >80% regularly follow 1-19 patients; 58% of hepatologists collaborate with palliative care physicians in the management of patients, 55% of palliative care physicians take care of patients without the aid of hepatologists. Management of cirrhosis differed significantly between the two groups in terms of prescription of albumin, esophagogastroduodenoscopy, anti-viral treatment, anticoagulation, indication to paracentesis and management of encephalopathy. Full-dose acetaminophen is widely used among hepatologists, while opioids are commonly used by both categories, at full dosage, regardless of liver function., Conclusions: This survey highlights significant differences in the approach to patients with liver transplantation- ineligible end-stage hepatocellular carcinoma, reinforcing the need for shared guidelines and further studies on palliative care in the setting., Competing Interests: Declaration of conflicting interestThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: M.

Abstract

Background and Aims: The efficacy of systemic therapy for unresectable advanced hepatocellular carcinoma (aHCC) has not been proven in patients with Child-Pugh (C-P) B cirrhosis. Nevertheless, in real-world these patients are treated both with tyrosine kinase inhibitors (TKIs) and with metronomic capecitabine (MC). This study aimed to compare sorafenib and MC outcomes versus best supportive care (BSC) in C-P B patients., Method: Between 2008 and 2020, among 774 C-P B patients with aHCC not amenable/responsive to locoregional treatments, 410 underwent sorafenib, 62 MC, and 302 BSC. The propensity score matching method was used to correct the baseline unbalanced prognostic factors., Results: In the unmatched population, median OS was 9.7 months in patients treated with sorafenib, 8.0 with MC, and 3.9 months with BSC. In sorafenib vs. BSC-matched patients (135 couples), median OS was 7.3 (4.9-9.6) vs. 3.9 (2.6-5.2) months (p<0.001). ECOG-Performance Status, tumor size, macrovascular invasion, AFP, treatment-naive, and sorafenib were independent predictors of survival. In MC vs. BSC-matched patients (40 couples), median OS was 9.0 (0.2-17.8) vs.3.0 (2.2-3.8) months (p<0.001). Median OS did not differ (p = 0.283) in sorafenib vs. MC-matched patients (55 couples)., Conclusion: C-P B patients with aHCC undergoing BSC have poor survival. Both Sorafenib and MC treatment improve their prognosis., Competing Interests: Conflict of interest GC declares consulting fees from Bayer, Roche, Ipsen, Merck Sharp & Dohme, Eisai, and AstraZeneca; FGF (advisory board, consulting fees): AbbVie, Bayer, Eisai, Gilead, MSD, and Intercept; EGG (advisory board, consulting fees): Astra Zeneca, Eisai, MSD, and Roche; GR (lectures, advisory board, consulting fees): Gilead, Alfa Wasserman, Intercept, and Eisai; FT (research grant, advisory board, consulting fees): Astra Zeneca, AbbVie, Bayer, Eisai, Gilead, MSD, and Roche.

Abstract

Recently, in Hepatocellular carcinoma (HCC) setting, the use of metformin has been associated to a trend toward worse response rate, overall survival and progression free survival in patients who received immunotherapy. The study population included individuals from both Eastern and Western regions with a confirmed diagnosis of HCC and receiving first line treatment with Atezolizumab plus bevacizumab or Lenvatinib. Univariate and multivariate analyses were performed by Cox proportional. For the analysis, patients were stratified based on their use of concomitant medication or not. At the time of database lock, 319 deaths were observed: 209 in the Lenvatinib cohort, 110 in the Atezolizumab plus bevacizumab cohort. In the Atezolizumab plus Bevacizumab arm, 50 (16.5%) patients were on chronic metformin use. At the univariate analysis for OS, patients who used metformin showed significantly shorter OS compared to patients who did not use metformin (HR 1.9, 95% CI 1.1-3.2). Multivariate analysis confirmed that patients in metformin group had significantly shorter OS compared to patients in no-metformin group (HR 1.9; 95% CI 1.1-3.1). At the univariate analysis for PFS, patients in metformin group had significantly shorter PFS compared to patients in no-metformin group (HR 1.6, 95% CI 1.0-2.6). Multivariate analysis confirmed that patients in metformin group had significantly shorter PFS compared to patients in no-metformin group (HR 1.7; 95% CI 1.1-2.7; p = 0.0147). No differences were reported in terms of ORR and DCR between patients in metformin group and those in no-metformin group. In the Lenvatinib cohort, 65 (15%) patients were recorded to chronically use metformin. No statistically significant differences in terms of both OS and PFS were found between patients in metformin group and patients in no-metformin group. This analysis unveils a negative prognostic role associated with metformin use specifically within the Atezolizumab plus Bevacizumab group., (© 2024. The Author(s).)

Abstract

Importance: The 2022 Barcelona Clinic Liver Cancer algorithm currently discourages liver resection (LR) for patients with multinodular hepatocellular carcinoma (HCC) presenting with 2 or 3 nodules that are each 3 cm or smaller., Objective: To compare the efficacy of liver resection (LR), percutaneous radiofrequency ablation (PRFA), and transarterial chemoembolization (TACE) in patients with multinodular HCC., Design, Setting, and Participants: This cohort study is a retrospective analysis conducted using data from the HE.RC.O.LE.S register (n = 5331) for LR patients and the ITA.LI.CA database (n = 7056) for PRFA and TACE patients. A matching-adjusted indirect comparison (MAIC) method was applied to balance data and potential confounding factors between the 3 groups. Included were patients from multiple centers from 2008 to 2020; data were analyzed from January to December 2023., Interventions: LR, PRFA, or TACE., Main Outcomes and Measures: Survival rates at 1, 3, and 5 years were calculated. Cox MAIC-weighted multivariable analysis and competing risk analysis were used to assess outcomes., Results: A total of 720 patients with early multinodular HCC were included, 543 males (75.4%), 177 females (24.6%), and 350 individuals older than 70 years (48.6%). There were 296 patients in the LR group, 240 who underwent PRFA, and 184 who underwent TACE. After MAIC, LR exhibited 1-, 3-, and 5-year survival rates of 89.11%, 70.98%, and 56.44%, respectively. PRFA showed rates of 94.01%, 65.20%, and 39.93%, while TACE displayed rates of 90.88%, 48.95%, and 29.24%. Multivariable Cox survival analysis in the weighted population showed a survival benefit over alternative treatments (PRFA vs LR: hazard ratio [HR], 1.41; 95% CI, 1.07-1.86; P = .01; TACE vs LR: HR, 1.86; 95% CI, 1.29-2.68; P = .001). Competing risk analysis confirmed a lower risk of cancer-related death in LR compared with PRFA and TACE., Conclusions and Relevance: For patients with early multinodular HCC who are ineligible for transplant, LR should be prioritized as the primary therapeutic option, followed by PRFA and TACE when LR is not feasible. These findings provide valuable insights for clinical decision-making in this patient population.

Abstract

Following the advent of direct-acting antivirals (DAAs), hepatitis C virus (HCV) infection can be cured in almost all infected patients. This has led to a number of clinical questions regarding the optimal management of the millions of patients cured of HCV. This position statement provides specific guidance on the appropriate follow-up after a sustained virological response in patients without advanced fibrosis, those with compensated advanced chronic liver disease, and those with decompensated cirrhosis. Guidance on hepatocellular carcinoma risk assessment and the management of extrahepatic manifestations of HCV is also provided. Finally, guidance is provided on the monitoring and treatment of reinfection in at-risk patients. The recommendations are based on the best available evidence and are intended to help healthcare professionals involved in the management of patients after treatment for HCV., (Copyright © 2024 European Association for the Study of the Liver.

Abstract

Background and Aims: Unlike other malignancies, hepatic functional reserve competes with tumor progression in determining the risk of mortality from hepatocellular carcinoma (HCC). However, the relative contribution of hepatic decompensation over tumor progression in influencing overall survival (OS) has not been assessed in combination immunotherapy recipients., Approach and Results: From the AB-real observational study (n = 898), we accrued 571 patients with advanced/unresectable hepatocellular carcinoma, Child-Pugh A class treated with frontline atezolizumab + bevacizumab (AB). Hepatic decompensation and tumor progression during follow-up were studied in relationship to patients' OS using a time-dependent Cox model. Baseline characteristics were evaluated as predictors of decompensation in competing risks analysis. During a median follow-up of 11.0 months (95% CI: 5.1-19.7), 293 patients (51.3%) developed tumor progression without decompensation, and 94 (16.5%) developed decompensation. In multivariable time-dependent analysis, decompensation (HR: 19.04, 95% CI: 9.75-37.19), hepatocellular carcinoma progression (HR: 9.91, 95% CI: 5.85-16.78), albumin-bilirubin (ALBI) grade 2/3 (HR: 2.16, 95% CI: 1.69-2.77), and number of nodules >3(HR: 1.63, 95% CI: 1.28-2.08) were independently associated with OS. Pretreatment ALBI grade 2/3 (subdistribution hazard ratio [sHR]: 3.35, 95% CI: 1.98-5.67) was independently associated with decompensation, whereas viral etiology was protective (sHR: 0.55, 95% CI: 0.34-0.87). Among patients with viral etiology, effective antiviral treatment was significantly associated with a lower risk of decompensation (sHR: 0.48, 95% CI: 0.25-0.93)., Conclusions: Hepatic decompensation identifies patients with the worst prognosis following AB and is more common in patients with baseline ALBI >1 and nonviral etiology. Effective antiviral treatment may protect from decompensation, highlighting the prognostic disadvantage of patients with nonviral etiologies and the importance of multidisciplinary management to maximize OS., (Copyright © 2024 American Association for the Study of Liver Diseases.)

Abstract

Background & Aims: Chronic hepatitis D virus (HDV) often leads to end-stage liver disease and hepatocellular carcinoma (HCC). Comprehensive data pertaining to large populations with HDV and HCC are missing, therefore we sought to assess the characteristics, management, and outcome of these patients, comparing them to patients with hepatitis B virus (HBV) infection., Methods: We analysed the Italian Liver Cancer database focusing on patients with positivity for HBV surface antigen and anti-HDV antibodies (HBV/HDV, n = 107) and patients with HBV infection alone (n = 588). Clinical and oncological characteristics, treatment, and survival were compared in the two groups., Results: Patients with HBV/HDV had worse liver function [Model for End-stage Liver Disease score: 11 vs. 9, p < .0001; Child-Turcotte-Pugh score: 7 vs. 5, p < .0001] than patients with HBV. HCC was more frequently diagnosed during surveillance (72.9% vs. 52.4%, p = .0002), and the oncological stage was more frequently Milan-in (67.3% vs. 52.7%, p = .005) in patients with HBV/HDV. Liver transplantation was more frequently performed in HBV/HDV than in HBV patients (36.4% vs. 9.5%), while the opposite was observed for resection (8.4% vs. 20.1%, p < .0001), and in a competing risk analysis, HBV/HDV patients had a higher probability of receiving transplantation, independently of liver function and oncological stage. A trend towards longer survival was observed in patients with HBV/HDV (50.4 vs. 44.4 months, p = .106)., Conclusions: In patients with HBV/HDV, HCC is diagnosed more frequently during surveillance, resulting in a less advanced cancer stage in patients with more deranged liver function than HBV alone. Patients with HBV/HDV have a heightened benefit from liver transplantation, positively influencing survival., (© 2024 The Authors. Liver International published by John Wiley & Sons Ltd.)

Abstract

Background: In the context of patients with hepatocellular carcinoma (HCC) treated with systemic therapy, the correlation between the appearance of adverse events (AEs) and reported efficacy outcomes is well-known and widely investigated. From other pathological settings, we are aware of the prognostic and predictive value of the occurrence of immune-related AEs in patients treated with immune-checkpoint inhibitors., Objective: This retrospective multicenter real-world study aims to investigate the potential prognostic value of AEs in patients with HCC treated with atezolizumab plus bevacizumab in the first-line setting., Patients and Methods: The study population consisted of 823 patients from five countries (Italy, Germany, Portugal, Japan, and the Republic of Korea)., Results: Of the patients, 73.3% presented at least one AE during the study period. The most common AEs were proteinuria (29.6%), arterial hypertension (27.2%), and fatigue (26.0%). In all, 17.3% of the AEs were grade (G) 3. One death due to bleeding was reported. The multivariate analysis confirmed the appearance of decreased appetite G < 2 [versus G ≥ 2; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.13-0.90; p < 0.01] and immunotoxicity G < 2 (versus G ≥ 2; HR: 0.70; 95% CI 0.24-0.99; p = 0.04) as independent prognostic factors for overall survival, and the appearance of decreased appetite G < 2 (versus G ≥ 2; HR: 0.73; 95% CI 0.43-0.95; p = 0.01), diarrhea (yes versus no; HR: 0.57, 95% CI 0.38-0.85; p = 0.01), fatigue (yes versus no; HR: 0.82, 95% CI 0.65-0.95; p < 0.01), arterial hypertension G < 2 (versus G ≥ 2; HR: 0.68, 95% CI 0.52-0.87; p < 0.01), and proteinuria (yes versus no; HR: 0.79, 95% CI 0.64-0.98; p = 0.03) as independent prognostic factors for progression-free survival., Conclusions: As demonstrated for other therapies, there is also a correlation between the occurrence of AEs and outcomes for patients with HCC for the combination of atezolizumab plus bevacizumab., (© 2024.

Abstract

Antiangiogenics are associated with an increased risk of major adverse cardiac and cerebrovascular events (MACE). The identification of at-risk subjects is relevant in the case of hepatocellular carcinoma (HCC), for which anti-angiogenic TKIs and bevacizumab are used in first and subsequent lines of therapy, to select alternative drugs for patients with excessive risk. We verified the ability to predict MACE in sorafenib-treated patients of the 2022 European Society of Cardiology (ESC-2022) score for anti-angiogenics and the recently proposed CARDIOSOR score. A retrospective analysis was conducted of prospectively collected data of the ARPES and ITA.LI.CA databases. All patients received sorafenib for unresectable HCC from 2008 to 2018. Baseline information to calculate the ESC-2022 and CARDIOSOR scores and registration of evolutive events (including MACE) were available for all patients. The predictive ability of both scores was verified using competing risk regressions and tests for goodness of fit. This study included 843 patients (median follow-up 11.3 months). Thirty-four (4.0%) patients presented a MACE. The four-tier ESC-2022 classification showed a progressive risk increase for every class (cumulative risk 1.7%, 2.7%, 4.3%, and 15.0% in the low, medium, high, and high-risk tiers, respectively). The dichotomous CARDIOSOR scale identified a high-risk group with a fourfold increased risk of MACE (sHR 4.66, p = 0.010; cumulative risk 3.8% and 16.4%). ESC-2022 showed a better goodness of fit compared to the CARDIOSOR score [C-index 0.671 (0.583-0.758) vs 0.562 (0.501-0.634), p = 0.021], but this gap was eliminated using the linear version of CARDIOSOR. Both the ESC-2022 and CARDIOSOR scores discriminated patients at increased risk for MACE. The use of these scores in clinical practice should be encouraged, since therapeutic measures can mitigate the cardiovascular risk., (© 2024. The Author(s).)

Abstract

The indolent and aggressive behaviors of HCC might have a role in clinical trial (CT) results; however, the indolent HCC is less analyzed compared to others cancer. Indolent profile could be characterized as follows: (1) patients with low risk of progression itself due to the HCC molecular profile and/or due to the interaction between cancer cell their microenvironment; (2) patients who achieve objective response or present spontaneous regression; and (3) patients who develop radiological progression with no consequence on either the liver function or general status, and without trigger a change in the tumor stage. Patients with "indolent HCC" generally never develop cancer-related symptoms neither die for HCC-related causes. Thus, we hypothesize that the imbalance in the proportion of "indolent" versus "aggressive HCC" between arms or the underestimation/overestimation of HCC behavior at baseline in single-arm CT could be associated with CT failure or under-overestimation of trial results. The "indolent progression" may also explain the discrepancy between radiological progression-based end points and survival. Moreover, we discuss the related causes that explain the indolent profile of HCC and propose (1) refining the progression-related end point by the pattern of progression to minimize the limitations of the current end points; (2) considering alternative statistical tools for survival analysis such as milestone survival, or restricted mean survival time to capture the value of indolent HCC. According to these considerations, we propose incorporating novel end points into the single arm of phase I/II CT as exploratory analysis or as a secondary end point in phase III CT., (Copyright © 2023 The Author(s).

Abstract

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer death worldwide and its prognosis is highly heterogeneous, being related not only to tumour burden but also to the severity of underlying chronic liver disease. Moreover, advances in systemic therapies for HCC have increased the complexity of patient management. Randomised-controlled trials represent the gold standard for evidence generation across all areas of medicine and especially in the oncology field, as they allow for unbiased estimates of treatment effect without confounders. Observational studies have many problems that could reduce their internal and external validity. However, large prospective (well-conducted) observational real-world studies can detect rare adverse events or monitor the occurrence of long-term adverse events. How best to harness real world data, which refers to data generated from the routine care of patients, and real-world 'evidence', which is the evidence generated from real-world data, represents an open challenge. In this review article, we aim to provide an overview of the benefits and limitations of different study designs, particularly focusing on randomised-controlled trials and observational studies, to address important and not fully resolved questions in HCC research., (Copyright © 2024 The Author(s).

Abstract

Introduction: The impact of etiology on response to immunotherapy in advanced hepatocellular carcinoma (HCC) is being debated, with contrasting findings between early and recent post hoc analyses of IMbrave-150 and metanalyses of clinical trials of PD-1/PD-L1 blockers. As a results, it is not clear whether the first-line systemic treatment atezolizumab plus bevacizumab (A + B) is equally effective in viral and nonviral patients., Methods: We retrospectively analyzed 885 HCC patients treated with the first-line A + B from multiple centers from Eastern and Western countries, 53.9% having viral and 46.1% nonviral etiology. Baseline clinical and laboratory characteristics were analyzed with uni- and multivariate models to explore potential differences on overall survival (OS), time-to-progression (TTP), disease control rates (DCRs) based on etiology and to identify putative prognostic factors in etiology subgroups. Treatment toxicities and access to the second-line treatments and outcomes were also reported and compared between etiologies., Results: Overall, no statistically significant differences were found in median OS (mOS: viral 15.9 months; nonviral 16.3 months), TTP (mTTP: viral 8.3 months; nonviral 7.2 months), and DCRs (viral 78.1%; nonviral 80.8%) based on etiology. Prognostic factors of survival and progression were mainly shared between viral and nonviral etiologies, including alpha-fetoprotein, aspartate transaminase, neutrophil-to-lymphocyte ratio (NLR) and ALBI score. Exploratory analyses highlighted a possible stronger association of immunological factors, i.e., NLR and eosinophil count, to treatment outcomes in viral patients. The toxicity profile, the access to and type of the second-line treatments and their outcome in terms of OS almost overlap in the two etiology subgroups., Conclusion: Atezolizumab plus bevacizumab efficacy does not vary according to underlying etiology of HCC in a multicenter, real-world population, matching recent post hoc findings from the IMbrave-150 trial. Preliminary analyses suggest that some prognostic factors differ between viral and nonviral patients, potentially due to biological and immunological differences. Prospective and comparative trials stratifying by etiology are warranted to validate these findings and guide clinical practice., Competing Interests: Andrea Casadei-Gardini has received grants and personal fees from MSD, Eisai, Bayer and is an advisor for MSD, Eisai, Bayer, Bristol-Myers Squibb, AstraZeneca and GSK.

Abstract

Atezolizumab plus bevacizumab (AB) and lenvatinib can be alternatively used as first-line systemic treatment of unresectable hepatocellular carcinoma (HCC). However, no direct comparison of the two regimens has been performed in randomized clinical trials, making the identification of baseline differential predictors of response of major relevance to tailor the best therapeutic option to each patient. Baseline clinical and laboratory characteristics of real-world AB-treated HCC patients were analyzed in uni- and multivariate analyses to find potential prognostic factors of overall survival (OS). Significant variables were incorporated in a composite score (α-FAtE) and it was tested for specificity and sensitivity in receiver operating characteristic (ROC) curve and in multivariate analysis for OS. The score was applied in uni- and multivariate analyses for OS of a comparable lenvatinib-treated HCC population. Finally, comparison between treatments was performed in patients with low and high α-FAtE scores and predictivity estimated by interaction analysis. Time-to-progression (TTP) was a secondary endpoint. OS of AB-treated HCC patients was statistically longer in those with α-fetoprotein <400 ng/mL (HR 0.62, p = .0407), alkaline phosphatase (ALP) <125 IU/L (HR 0.52, p = .0189) and eosinophil count ≥70/μL (HR 0.46, p = .0013). The α-FAtE score was generated by the sum of single points attributed to each variable among the above reported. In ROC curve analysis, superior sensitivity and specificity were achieved by the score compared to individual variables (AUC 0.794, p < .02). Patients with high score had longer OS (HR 0.44, p = .0009) and TTP (HR 0.34, p < .0001) compared to low score if treated with AB, but not with lenvatinib. Overall, AB was superior to lenvatinib in high score patients (HR 0.55, p = .0043) and inferior in low score ones (HR 1.75, p = .0227). At interaction test, low α-FAtE score resulted as negative predictive factor of response to AB (p = .0004). In conclusion, α-FAtE is a novel prognostic and predictive score of response to first-line AB for HCC patients that, if validated in prospective studies, could drive therapeutic choice between lenvatinib and AB., (© 2023 UICC.)

Abstract

Background & Aims: Immune-related liver injury (irLI) is commonly observed in patients with cancer treated with immune checkpoint inhibitors (ICIs). We aimed to compare the incidence, clinical characteristics, and outcomes of irLI between patients receiving ICIs for hepatocellular carcinoma (HCC) vs. other solid tumours., Methods: Two separate cohorts were included: 375 patients with advanced/unresectable HCC, Child-Pugh A class treated with first-line atezolizumab+bevacizumab from the AB-real study, and a non-HCC cohort including 459 patients treated with first-line ICI therapy from the INVIDIa-2 multicentre study. IrLI was defined as a treatment-related increase of aminotransferase levels after exclusion of alternative aetiologies of liver injury. The incidence of irLI was adjusted for the duration of treatment exposure., Results: In patients with HCC, the incidence of any grade irLI was 11.4% over a median treatment exposure of 4.4 months (95% CI 3.7-5.2) vs. 2.6% in the INVIDIa-2 cohort over a median treatment exposure of 12.4 months (95% CI 11.1-14.0). Exposure-adjusted-incidence of any grade irLI was 22.1 per 100-patient-years in patients with HCC and 2.1 per 100-patient-years in patients with other solid tumours (p <0.001), with median time-to-irLI of 1.4 and 4.7 months, respectively. Among patients who developed irLI, systemic corticosteroids were administered in 16.3% of patients with HCC and 75.0% of those without HCC (p <0.001), and irLI resolution was observed in 72.1% and 58.3%, respectively (p = 0.362). In patients with HCC, rates of hepatic decompensation and treatment discontinuation due to irLI were 7%. Grade 1-2 irLI was associated with improved overall survival only in patients with HCC (hazard ratio 0.53, 95% CI 0.29-0.96)., Conclusions: Despite higher incidence and earlier onset, irLI in patients with HCC is characterised by higher rates of remission and lower requirement for corticosteroid therapy (vs. irLI in other solid tumours), low risk of hepatic decompensation and treatment discontinuation, not negatively affecting oncological outcomes., Impact and Implications: Immune-related liver injury (irLI) is common in patients with cancer receiving immune checkpoint inhibitors (ICIs), but whether irLI is more frequent or it is associated with a worse clinical course in patients with hepatocellular carcinoma (HCC), compared to other tumours, is not known. Herein, we compared characteristics and outcomes of irLI in two prospective cohorts including patients treated with ICIs for HCC or for other oncological indications. irLI is significantly more common and it occurs earlier in patients with HCC, also after adjustment for duration of treatment exposure. However, outcomes of patients with HCC who developed irLI are not negatively affected in terms of requirement for corticosteroid therapy, hepatic decompensation, treatment discontinuation and overall survival., (Copyright © 2023 The Author(s).

Abstract

Background: Data concerning the use of lenvatinib in very old patients (≥ 80 years) are limited, although the incidence of hepatocellular carcinoma (HCC) in this patient population is constantly increasing., Objective: This analysis aimed to evaluate the efficacy and safety of lenvatinib in a large cohort of very old patients (≥ 80 years) with unresectable HCC., Patients and Methods: The study was conducted on a cohort of 1325 patients from 46 centers in four Western and Eastern countries (Italy, Germany, Japan, and the Republic of Korea) who were undergoing first-line treatment with lenvatinib between July 2010 and February 2022. Patients were stratified according to age as very old (≥ 80 years) and not very old (< 80 years)., Results: The median overall survival (OS) was 15.7 months for patients < 80 years old and 18.4 months for patients ≥ 80 years old [hazard ratio (HR) = 1.02, 95% confidence interval (CI) 0.84-1.25, p = 0.8281]. Median progression free survival (PFS) was 6.3 months for patients < 80 years old and 6.5 months for patients ≥ 80 years old (HR = 1.07, 95% CI 0.91-1.25, p = 0.3954). No differences between the two study groups were found in terms of disease control rate (DCR; 80.8% versus 78.8%; p = 0.44) and response rate (RR; 38.2% versus 37.9%; p = 0.88). Patients < 80 years old experienced significantly more hand-foot skin reaction (HFSR) grade ≥ 2 and decreased appetite grade ≥ 2. Conversely, patients ≥ 80 years old experienced significantly more fatigue grade ≥ 2. In the very old group, parameters associated with prognosis were AFP, albumin-bilirubin (ALBI) grade, Barcelona Clinic Liver Cancer (BCLC), and Child-Pugh score. BCLC stage was the only independent predictor of overall survival (OS; HR = 1.59, 95% CI 1.11-2.29, p = 0.01115)., Conclusions: Our study highlights the same efficacy and safety of lenvatinib between very old and not very old patients., (© 2024.

Abstract

Background and Aims: Hepatocellular carcinoma (HCC) recurrence is common in patients treated with liver resection (LR). In this study, we aimed to evaluate the incidence and preoperative predictors of non-transplantable recurrence in patients with single HCC ≤5 cm treated with frontline LR., Methods: From the Italian Liver Cancer (ITA.LI.CA) database, 512 patients receiving frontline LR for single HCC ≤5 cm were retrieved. Incidence and predictors of recurrence beyond Milan criteria (MC) and up-to-seven criteria were compared between patients with HCC <4 and ≥4 cm., Results: During a median follow-up of 4.2 years, the overall recurrence rate was 55.9%. In the ≥4 cm group, a significantly higher proportion of patients recurred beyond MC at first recurrence (28.9% vs. 14.1%; p < 0.001) and overall (44.4% vs. 25.2%; p < 0.001). Similar results were found considering recurrence beyond up-to-seven criteria. Compared to those with larger tumours, patients with HCC <4 cm had a longer recurrence-free survival and overall survival. HCC size ≥4 cm and high alpha-fetoprotein (AFP) level at the time of LR were independent predictors of recurrence beyond MC (and up-to-seven criteria). In the subgroup of patients with available histologic information (n = 354), microvascular invasion and microsatellite lesions were identified as additional independent risk factors for non-transplantable recurrence., Conclusions: Despite the high recurrence rate, LR for single HCC ≤5 cm offers excellent long-term survival. Non-transplantable recurrence is predicted by HCC size and AFP levels, among pre-operatively available variables. High-risk patients could be considered for frontline LT or listed for transplantation even before recurrence., (© 2023 The Authors. Liver International published by John Wiley & Sons Ltd.)

Abstract

Systemic treatment for advanced hepatocellular carcinoma (HCC) has been revolutionized over the last few years following the approval of immune checkpoint inhibitors (ICI). Despite the promising survival extension seen with ICI combination regimens, responses are not universally seen and the optimal partner for programmed cell death 1 pathway inhibitors remains to be identified. Even fewer encouraging results have been demonstrated with ICI used for monotherapy. Several mechanisms of resistance have been described so far, involving characteristics of cancer cells (intrinsic mechanisms) and of the surrounding tumor microenvironment (extrinsic mechanisms). Factors related to therapy may also contribute to the development of resistance. Increasing research efforts are being dedicated to the discovery of novel approaches and targets to overcome resistance, some of which may be introduced into clinic in the future. Herein we describe a selection of resistance mechanisms that have been involved in impairing response to ICI and propose potential therapeutic approaches to overcome resistance., Competing Interests: CC received speaker fees from Eisai, MSD, and Ipsen.

Abstract

Introduction: The aim of this retrospective proof-of-concept study was to compare different second-line treatments for patients with hepatocellular carcinoma and progressive disease (PD) after first-line lenvatinib or atezolizumab plus bevacizumab., Materials and Methods: A total of 1381 patients had PD at first-line therapy. 917 patients received lenvatinib as first-line treatment, and 464 patients atezolizumab plus bevacizumab as first-line., Results: 49.6% of PD patients received a second-line therapy without any statistical difference in overall survival (OS) between lenvatinib (20.6months) and atezolizumab plus bevacizumab first-line (15.7months; p = 0.12; hazard ratio [HR]= 0.80). After lenvatinib first-line, there wasn't any statistical difference between second-line therapy subgroups (p = 0.27; sorafenib HR: 1; immunotherapy HR: 0.69; other therapies HR: 0.85). Patients who underwent trans-arterial chemo-embolization (TACE) had a significative longer OS than patients who received sorafenib (24.7 versus 15.8months, p < 0.01; HR=0.64). After atezolizumab plus bevacizumab first-line, there was a statistical difference between second-line therapy subgroups (p < 0.01; sorafenib HR: 1; lenvatinib HR: 0.50; cabozantinib HR: 1.29; other therapies HR: 0.54). Patients who received lenvatinib (17.0months) and those who underwent TACE (15.9months) had a significative longer OS than patients treated with sorafenib (14.2months; respectively, p = 0.01; HR=0.45, and p < 0.05; HR=0.46)., Conclusion: Approximately half of patients receiving first-line lenvatinib or atezolizumab plus bevacizumab access second-line treatment. Our data suggest that in patients progressed to atezolizumab plus bevacizumab, the systemic therapy able to achieve the longest survival is lenvatinib, while in patients progressed to lenvatinib, the systemic therapy able to achieve the longest survival is immunotherapy., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: A.C.G. is an advisor for AstraZeneca, Bayer, Bristol-Myers Squibb, Eisai, GSK, and MSD; received grants and personal fees from Bayer, Eisai, and MSD.
